The White Sox optioned Quero to Triple-A Charlotte on Monday, Mike McGraw of the Chicago Daily Herald reports.

After acquiring catcher Joey Bart on Monday, the White Sox have optioned Quero to Charlotte. In 193 plate appearances this season, Quero has slashed .194/.257/.235 with two home runs and 16 RBI. The White Sox will operate with Bart and Drew Romo behind the plate for now, with Kyle Teel (ankle) on the injured list for an extended period.

The Red Sox acquired Gutierrez and left-hander Erik Miller to the Giants on Monday in exchange for infielder Marcelo Mayer (forearm).

A 21-year-old outfielder, Gutierrez is slashing .271/.385/.441 with nine home runs, 26 steals and a 19.6 percent strikeout rate in 83 games at High-A. Despite his high stolen-base total, Gutierrez likely projects as a left fielder at the big-league level, so he needs to continue producing to have a shot as an everyday player.

The Marlins acquired Vodnik from the Rockies on Monday in exchange for Connor Norby and Aiden May, Jeff Passan of ESPN reports.

Vodnik has logged a 5.25 ERA and 26:19 K:BB over 36 frames this season for the Rockies. The 26-year-old is a hard thrower and boasts a career 54.3 percent groundball rate, but a 16 percent strikeout rate in 2026 is disheartening. Vodnik could get a chance to fill in a leverage role in the Miami bullpen, though Pete Fairbanks should remain the team's closer.

Pittsburgh recalled Eisert from Triple-A Indianapolis on Monday.

After being optioned to Indianapolis last Wednesday, Eisert will rejoin the Pirates less than a week later with Mitch Keller (arm) going on the 60-day injured list in a corresponding move. Over 32 appearances in the majors this season between stops with the White Sox and Pirates, the left-handed reliever owns a 6.29 ERA, 1.40 WHIP and 40:12 K:BB across 34.1 innings.

Basabe (forearm) will start at second base and bat seventh in Monday's game versus the Rangers.

Basabe was lifted from Sunday's 5-4 loss to the Padres after being hit on the left forearm by a pitch, but he's back in the lineup a day later. He'll be making his third consecutive start and has gone 3-for-9 with a pair of home runs early on in his stint with the Giants. With the Giants trading away Luis Arraez and Heliot Ramos ahead of Monday's deadline, Basabe could get the chance to play on at least a semi-regular basis in the short term.

The Pirates placed Keller on the 60-day injured list Monday due to a right arm teres major muscle injury.

Keller's move to the IL comes just one day after he was lit up for seven earned runs on six hits and four walks in just two innings during Sunday's 10-2 loss to the Reds. The Pirates haven't provided an official recovery timeline for Keller, but his move to the 60-day IL makes him ineligible to be activated until Oct. 2, and the regular season concludes Sept. 27. The Pirates recalled Brandon Eisert from Triple-A Indianapolis to join the roster as a replacement for Keller, who ends his eighth MLB season with a 6-8 record, 5.29 ERA, 1.37 WHIP and 89:42 K:BB over 115.2 innings.

The Pirates traded Bidois, Hyun Seung Lee and Brian Sanchez to the Marlins on Monday in exchange for Lake Bachar, Will Sammon of The Athletic reports.

A 25-year-old righty reliever, Bidois was optioned to Triple-A on July 1. He logged a 6.32 ERA, 1.98 WHIP and 20:12 K:BB in 15.2 innings out of the big-league bullpen.

The Tigers acquired Wolf and left-hander Kash Mayfield from the Padres on Monday in exchange for right-hander Casey Mize and infielder Gage Workman, Kevin Acee of The San Diego Union-Tribune reports.

Mayfield is the clear headliner in this deal, as Wolf had already been designated for assignment by San Diego back in 2024. A 27-year-old southpaw, Wolf has logged a 7.05 ERA, 1.67 WHIP and 90 strikeouts in 89.1 innings this season in the Pacific Coast League.

The Pirates acquired Yates from the Angels on Monday in exchange for right-hander Kyle Robinson, Ken Rosenthal of The Athletic reports.

Yates has logged a 3.95 ERA and 36:12 K:BB over 27.1 innings for the Halos this season. The 39-year-old will likely slot into a setup role as part of a retooled Pittsburgh bullpen. Yates will become a free agent after the season.

The Tigers acquired Mayfield and left-hander Jackson Wolf from the Padres on Monday in exchange for right-hander Casey Mize and infielder Gage Workman, Kevin Acee of The San Diego Union-Tribune reports.

Mayfield, 21, sits in the low-90s with his fastball, but the rest of his arsenal is mid-rotation caliber, headlined by a plus changeup. The 6-foot-4 southpaw posted a 3.54 ERA, 1.16 WHIP and 62 strikeouts in 53.1 innings across 15 starts at High-A Fort Wayne this season.
